Endothelium corneum gigeriae galli specific polypeptide and application thereof in identification of endothelium corneum gigeriae galli

An endothelium corneum gigeriae galli specific polypeptide and an application thereof in the identification of endothelium corneum gigeriae galli. By using high-resolution liquid chromatography-mass spectrometry technology and combining proteomics theory, a characteristic polypeptide of the endothelium corneum gigeriae galli is screened out, and the use of the characteristic polypeptide can quickly and accurately identify an endothelium corneum gigeriae galli component in an endothelium corneum gigeriae galli sample (e.g. an endothelium corneum gigeriae galli standard decoction), and can quickly identify whether the endothelium corneum gigeriae galli standard decoction is mixed with the membrane of poultry gizzard such as the membrane of duck gizzard, the membrane of goose gizzard, and the membrane of pigeon gizzard.
